0.17.0

Major changes:

We've rewritten the Context Menu plugin, changes are as follows:

• Context Menu plugin is now accesible from hot.getPlugin('contextMenu') (was hot.contextMenu)
• All of Context Menu's actions can now be triggered using the executeCommand method. For example:

hot.getPlugin('contextMenu').executeCommand('alignment:middle');

hot.getPlugin('contextMenu').executeCommand('make_read_only');

• There is now an option to hide a Context Menu entry using a hidden property (defined as a function, analogously to name or callback)
• Context Menu's SEPARATOR constant is now accessible through Handsontable.plugins.ContextMenu.SEPARATOR (was Handsontable.ContextMenu.SEPARATOR)
• Submenu's class name changed from htContextSubMenu_{...} to htContextMenuSub_{...}
